JP 11-318204 A

  However, in the case of growing using the planting member in Patent Document 1 described above, for example, in order to plant a rooftop of a factory, amusement facility, warehouse, etc. having a large area, a large area is planted at once. Requires planting material.

  And in order to produce this planting member, a period of upbringing and curing for about two months is required in a greenhouse or the like. Therefore, when a large amount of planting members are required at once, it is necessary to secure a large-area greenhouse or the like. Still, a large amount of planting members may not be procured, and the construction period may be significantly prolonged, or the greening area may be divided and the divided areas may be greened.

  In addition, the method of planting by directly laying soil on the rooftop or the like requires various treatments such as root resistance, waterproofing treatment, and soil loading at the site, which requires a long construction period and high costs. Furthermore, once planted, it is very difficult to remove or replant.

  An object of the present invention is to provide a plant growing method and a planting member that solve the above-mentioned problems, are easy to construct and dismantle, are suitable for greening a large area, and can be grown at low cost. is there.

  The technical characteristics of the plant growing method according to the present invention for achieving the above object include a step of arranging a plurality of porous ceramic substrates without gaps, and laminating a fibrous brushed material on the porous ceramic substrates. A step of mixing a soil for growing a plant in the brushed material and mixing any of plant seeds, foliage, or spores into the soil, and a step of covering the soil with a net And having the plant germinate and root to grow.

  Further, the technical feature of the planting member according to the present invention is that a fibrous brushed material is laminated on a porous ceramic substrate, and the soil and plant seeds or foliage for growing plants are mixed in the brushed material. Then, the net is covered with a net, and the plant is germinated and rooted to grow.

  According to the method for growing a plant according to the present invention, the foliage or a plant that has grown to some extent is prevented from being scattered by the net, so that the land and growing plants can be efficiently fixed without being scattered by the wind. It is possible to plant a large-scale area directly on the rooftop of a building at low cost.

  Moreover, according to the planting member according to the present invention, by using a net in an open space that does not use a greenhouse, it can be grown and trained while suppressing the scattering of foliage or plants that have grown to some extent, and transported to other places. Can be planted.

The present invention will be described in detail based on the embodiments shown in the drawings.
First, as shown in FIG. 1, a plurality of porous ceramic substrates 1 are arranged on the roof of a building to be greened without any gaps. In FIG. 1, four porous ceramic substrates 1 are shown, and the other substrates 1 are not shown. Steps 1a and 1b are provided on the side surface of the porous ceramic substrate 1 so that the adjacent substrates 1 are not displaced when a plurality of substrates 1 are arranged. They can be easily arranged by simply overlapping 1a and 1b. In the embodiment, the step portions 1a and 1b in the cross-sectional direction have been described, but step portions (not shown) can be provided in the vertical cross-sectional direction as well as in the cross-sectional direction.

  The porous ceramic substrate 1 is, for example, a rectangular plate having a specific gravity of 0.5 to 0.7, a thickness of about 25 to 60 mm, and a side length of about 1 × 2 m, and has porous continuous pores inside. Has water retention. For example, when the substrate 1 is fired at about 1000 ° C. as foamed ceramics using diatomaceous earth as a raw material, a combination of μm-sized pores inherent in the diatomaceous earth and mm-sized pores in the foamed ceramics causes the surroundings of large flat pores to be reduced. A continuous through-hole structure in which fine sponge-like pores of 10 to 100 μm are surrounded is generated. And by the above-mentioned baking, pores equivalent to the inside are exposed on the top surface, and pores on the bottom surface are extremely miniaturized.

  This porous ceramic substrate 1 is an inorganic material and does not elute organic chemical substances or heavy metals, and is excellent in water permeability, water retention, sound absorption, heat insulation, workability, and water absorption. In particular, it has a water retention capacity of about 50% of its own weight, and has the property of draining water above saturation.

  As shown in FIG. 2, a synthetic resin film 2 for waterproofing is attached in advance to the lower surface of the porous ceramic substrate 1. Prior to the placement of the substrate 1, the construction surface is formed by the roll-shaped film 2. You may cover and mount the base | substrate 1 on it. Furthermore, a roll-like raising material 3 having a width of about 1 mm and a length of about 30 m, in which a large number of synthetic resin fibers are intertwined, is stuck on the substrate 1 and laminated.

  Subsequently, the customer soil 4 made of lightweight volcanic gravel or the like is mixed in the raised material 3. It is preferable that this mineral 4 contains trace element minerals necessary for plant growth. In this way, by mixing the soil 4 into the brushed material 3, the soil 4 is not scattered, and secular changes such as compression and settlement of the soil 4 are prevented, thereby promoting plant root growth. It becomes a structure.

  Then, after the stalks and leaves 5 obtained by chopping the stalks and leaves of the plant are sown on the soil 4, the soil 4 is covered with a net 6 made of a synthetic resin as shown in FIG. Note that plant seeds and spores may be used in place of the foliage 5. Further, the foliage 5, seeds, and spores may be mixed in the customer soil 4 in advance, and the customer soil 4 may be mixed in the raised material 3.

  Then, by sprinkling water and causing germination and rooting from the foliage 5, a plant 5 ′ is grown from the foliage 5 as shown in FIG. 4. The root hairs of the plant 5 ′ are easily fixed by being entangled with the raised material 3, and can enter and grow into the continuous pores of the porous ceramic substrate 1. Further, by using the net 6, it is possible to prevent the soil, foliage 5 and growing plant 5 'from being scattered by the wind. By promoting the establishment of the plant 5 ′ with this net 6, it is suitable for greening in windy places such as buildings and factory rooftops.

  After the root hair of the plant 5 ′ has developed and has sufficiently settled on the brushed material 3 or the porous ceramic substrate 1, the net 6 may remain attached, or the net 6 and the hook 7 may be attached as shown in FIG. It may be removed.

  The plant 5 'to be cultivated may be a general flower, lawn or the like. For example, if a so-called sedum belonging to the family Acephalidae which is resistant to drying is used, it is resistant to drying, even under severe temperatures and harsh environments with little soil. Can be trained. For this reason, when it grows up on the rooftop of a building, etc., it is possible to save labor and water costs compared to the case of a conventional rooftop garden or the like.

  Since the porous ceramic substrate 1 has excellent water retention, the sedum can usually be grown only with moisture of rainwater, and almost no weeding or pruning work is required. As described above, once installed, except for the case where the net 6 is removed, etc., almost no human hands are required. Therefore, it is also suitable outside the high-level handrail where maintenance is difficult and in places where security is severe.

  Since this porous ceramic substrate 1 is excellent in heat insulation performance, for example, when used on the roof of a building that is easily influenced by the outside air temperature, the amount of indoor air-conditioning power consumption can be greatly reduced.

  Furthermore, in the case of greening using the plant growing method in the present embodiment, it is not necessary to pre-curve and grow planting members in advance in a greenhouse, etc., and can greatly reduce the cost and suddenly large-scale We can respond to requests for greening work.

  During construction and removal, it can be divided and transported for each of the porous ceramic substrate 1, the brushed material 3, the soil 4, the foliage 5, the net 6, and the hook 7. . In addition, since a plurality of bases 1 are laid, when a part of the base 1 plants wither or get sick, only the base 1 of the part is replaced with a new substrate 1. Thus, the plant 5 ′ can be newly cultivated or replaced with a planting member that has already been cultivated. The replaced porous ceramic substrate 1 can be reused in another place.

  In addition, in the present Example, although the case where it planted on the roof of a building was demonstrated, the porous ceramic base | substrate 1 can be directly arrange | positioned on the grounds, such as a garden, not necessarily on a building. In this case, since waterproofness is not required, the film 2 on the bottom surface of the base 1 is not necessary.

  In addition, since the method for growing plants in the present example is strong against wind using a net, planting members conventionally produced in a greenhouse are grown on fields, open spaces, building rooftops, etc. It is also possible to divide each ceramic ceramic substrate 1 and relocate it to the place to be greened. At this time, in order to make it easy to divide each porous ceramic substrate 1, the brushed material 3 is cut and laminated in advance for each size of the porous ceramic substrate 1, or a cut is made. It is preferable.

It is a perspective view in the state where a porous ceramic substrate was arranged. It is the side view which provided the synthetic resin film and the raising material in the porous ceramic base. It is a perspective view of the state where the net was stretched on the land. It is a perspective view of the state where the plant grew. It is a perspective view in the state where a net was removed.
